GRAFTING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 348,592, dated September 7, 1886. Application filed February 5, 1886. Serial No. 190.929. (Model.)

To all whom it may concern.-

Be it known that I, DARTUs B. SPEER, a citizen of the United States, residing at Blue Grass, in the county of Scott and State of Iowa, have invented a new and useful Im provement in Grafting-Machines, of which the following is a specication, reference being had to the accompanying drawings.

My invention relates to an improvement iu grafting-machines for cutting scions and roots, so that they may be spliced together; and it consists in the peculiar construction and cornbination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is an elevation of a grafting-machine embodying my invention, parts being broken away. Fig. 2 is a top plan view ofthe same. Fig. 3 is a detailed view. Fig. 4 is a diagram of the splice.

A represents a .stand or table having the legs B. A metallic brace or casting, C, is bolted to the legs on the rear corners of the table, and on a stud, D, that projects inwardly from the said casting is journaled a wheel, E.

F represents a treadle, that is journaled on a rod, G, which connects two of the legs of the table. A pitman, H, connects the treadle and the wheel.

I represents a transverse slot that is made in the top of the table, near the rear edge thereof, and K represents a frame on the upper side of the table. rlhis frame consists of a body part, L, arranged on one side of the slot, and end pieces, M, at the ends of the body part and extending across the ends of the slot, as shown at Fig. 2.

N represents guide-rods, that extend across the frame K, above the slot and in a vertical line with each other, the ends of the said rods being secured in the end pieces, M.

O represents a reciprocating cutter head or block, that works on the rods N, being provided with longitudinal openings, through which the said rods pass. In the ends of the cutter-head are'recessed buffers I?, which are made of rubber or other suitable material.

R represents a strap, which is secured to the periphery of the wheel by a screw, S. The ends of `the strap are crossed, as shown at Fig. l, and are secured to the opposite ends of the cutter-head by screws T. The upper edge of the wheel and the ends of the straps work in the slot I. The treadle is operated so as to cause the wheel to partly rotate first in one direction and then in the contrary direction, which causes the cutter-head to move back and forth on the guide-rods across the table, as will be very readily understood.

V represents notches on the upper edge of the body part L of the frame K, near the center thereof, to form rests and supports for the scion and root.

On the upper side of the cutter-head, near the center thereof, are secured cutting-knives V and X, by means of set-screws Z. The outer ends of these knives project from the front side of the'cutter-head and over the upper edge of the flange L. The knife XV is set at an incline, as shown at Fig. 3, so as to make a sloping cut, and the' knife X is horizontal, so as to make a split cut. The upper sides of the rests are each provided with a horizontal portion, o, for the knife X to pass over, and an inclined outer portion, o', for the knife W to pass over, as shown in Fig. 3. The cutting-edge of the knife XV travels in a higher plane than the knife X.

The operation of my invention is as follows: Thescion a and the root I) to be grafted together are held in the rests V by the operator, with their ends in the paths of the knives, and the cutter-head is caused to move across the table. As the knives pass over the rests they come in contact with the ends of the scion and root and slope and slit the ends of the said scion and root respectively, to enable them to be spliced together, as shown in Fig. 4.

By changing the construction and arrangement of the knives the machine maybe caused to cut the ends of the scions and roots in any manner desired, in order to adapt the machine for making splices in any of the well-known and preferred forms.

Having thus described myv claiml. rIhe combination, in a grafting-machine, of the table or stand, the frame provided with the rests or supports,the reciprocally-movable cutter-head, the knives attached thereto, the wheel, and means connecting the said wheel with the cutter head, to actuate the latter invention, I

IOO

when the Wheel is operated, sbstantially as described.

2. The combination, in a grafting-machine, of the table or stand, the frame provided with the rests or supports and the guide-rods, the reciprocally-movable cutter-head on the guiderods, the knives attached thereto, the Wheel, and the strap on the said Wheel, having its ends crossed and secured to the ends of the cutter-head, substantially as described.

3. The combination, in a grafting-machine, of the table or stand, the frame K, provided with rests or supports and the guide-rods, and the reciprocally-movable cutter-head on the guide-rods, and the knives, substantially as described.

4. The combination, in a grafting-machine, of the table or stand, the frame K, having the DARIUs B. sPEnn.
